A2.1

identify, through investigation using technology, the effect on the graph of $y=x^2$ of transformations (i.e., translations, reflections in the x-axis, vertical stretches or compressions) by considering separately each parameter $a$, $h$, and $k$ [i.e., investigate the effect on the graph of $y=x^2$ of $a$, $h$, and $k$ in $y=x^2+k$, $y=(x-h{)}^2$, and $y=a{x}^2$];
